Figure 1. 3D human fimbriae culture system supports secretory and ciliated epithelium.

Human fimbriae cultures encapsulated in alginate hydrogels retained normal tissue architecture for up to 7 days in culture, as demonstrated by comparative H&E staining. FTE was maintained as identified by cytokeratin 8 (CK8) staining. Further, both epithelial subtypes; secretory (PAX8) and ciliated (Ac. Tubulin). Scalebar equals 50 µm.
